A century ago, a small institution called Throop Polytechnic Institute dramatically reinvented itself, transforming from a manual arts academy to an engineering school, then expanding into a research institute. In 1920, it became the California Institute of Technology. In summer 2020, Caltech archivists gave a series of livestreamed presentations on the science, engineering, architecture, and community life of early Caltech. You can find below links to video of these presentations, and a bibliography of further reading.
